Abstract
In a fuzzy inference system comprising a plurality of fuzzy rules including input labels as antecedents, a min-max computing circuit for executing rain-max computation on input label grades is disclosed. The min-max computing circuit comprises an input label sorter (10) for sorting all input label grades in their magnitude order; a rule bits generating means for generating encoded rules(20), each of said encoded rules comprising a plurality of valid/invalid bits, each of which representing whether or not corresponding input label is included in the antecedent of each of said rules; and a min-max computing logic devices (30, 40) for executing min-max computations on the input label grades according to the grade's magnitude order.
